Klippel-Trenaunay-Weber syndrome and intramedullary cervical cavernoma: a very rare association. Case report

BACKGROUND

Klippel-Trenaunay-Weber syndrome is a rare mesodermal phakomatosis characterized by cutaneous hemangiomata, venous varicosities, and osseous-soft tissue hypertrophy of the affected limb. As the pathologic aspect of KTWS arises from the site in which malformations occur, the clinical picture varies widely from patients who complain for cosmetic reasons to patients with life-threatening lesions.

CASE DESCRIPTION

We describe a very rare case in which KTWS was associated with a cervical intramedullary cavernous angioma surgically treated.

CONCLUSION

This report confirms the wide range of expression of vascular abnormalities in neurocutaneous developmental diseases and the need of a careful multisystemic evaluation of these patients.

Life-threatening gross hematuria due to genitourinary manifestation of Klippel-Trenaunay syndrome

The Klippel-Trenaunay Syndrome (KTS) is defined as a triad of cutaneous capillary malformations, venous varicosities, bone and soft tissue hemi-hypertrophy. The urinary tract is involved in up to 10%. We report the clinical presentation and surgical management of a 9-year-old boy with extensive lympho-venous malformations of the bladder which led to massive recurrent gross hematuria.

Rare instance of gingival enlargement in Klippel-Trenaunay syndrome: a case report

Klippel-Trenaunay Syndrome is a rare congenital malformation that may include port-wine stain, soft tissue and bony hypertrophy, and venous malformations and lymphatic abnormalities. Although it usually involves the limbs, it may also rarely involve the head, neck, and orofacial regions. Despite its rarity, Klippel-Trenaunay Syndrome should be considered in the differential diagnosis of gingival enlargement. The condition can be easily recognized clinically, but further investigations including imaging studies have to be carried out in order to better understand the nature of the lesion. This report describes a case of gingival enlargement in Klippel-Trenaunay Syndrome in a 16-year-old female patient. The diagnosis of the condition was made based on the patient history, clinical and radiographic examination, computed tomography (CT), and angiogram.

Klippel Trenauney syndrome and reduction mammoplasty

Klippel Trenauney syndrome is a rare congenital abnormality that includes extremity hypertrophy. We report an unusual case of breast asymmetry due to unilateral chest and limb hypertrophy and describe successful unilateral breast reduction. We highlight the potential problems of surgery within this group and a management approach to minimise complications.

Popliteal arterial aneurysm associated with Klippel-Trénaunay syndrome: Case report and literature review

A 35-year-old woman with Klippel-Trénaunay syndrome developed a popliteal artery aneurysm in the affected extremity. The aneurysm was successfully treated by aneurysmectomy and bypass grafting with autologous saphenous vein. In Klippel-Trénaunay syndrome, angiodysplasia in the venous system is common. However, reports of an arterial aneurysm in a patient with Klippel-Trénaunay syndrome are extremely rare.

Anesthetic and obstetric considerations in a parturient with klippel-trenaunay syndrome

PURPOSE

To explain the considerations governing the anesthetic management of pregnant patients with Klippel-Trenaunay syndrome (KTS). Klippel-Trenaunay syndrome is a congenital vascular disease characterized by cutaneous hemangiomas, venous varicosities, and limb hypertrophy; and is associated with both hemorrhagic and thrombotic complications. The importance of this diagnosis, including the presence of neuraxial vascular anomalies, is often under-appreciated by both obstetric and anesthesia providers. While regional anesthetic management of patients with KTS has been discussed by others, we present a case in which regional anesthesia presented an unwarranted risk to the patient.

CLINICAL FEATURES

An obese, 18-yr-old parturient with a fetus in the breech position underwent Cesarean delivery at 35 weeks gestation secondary to evolving preeclampsia. Unfortunately, no neurovascular imaging of this patient's spine was available. The patient underwent an attempted external cephalic version, a failed obstetric induction, and, ultimately, a Cesarean delivery under general anesthesia. The resulting infant was without any stigmata of KTS. Both mother and infant did well during the course of their hospitalization, and were discharged home without incident.

CONCLUSIONS

The posterior cutaneous hemangiomas of KTS may be associated with underlying epidural and subdural vascular malformations. Disruption of these vascular anomalies during regional anesthesia may lead to neuraxial hematoma formation, which may be further compounded by a consumptive coagulopathy observed in some cases of KTS. If neuraxial vascular anomalies cannot be ruled out radiographically, regional anesthesia should be avoided. Additionally, regardless of the anesthetic technique chosen, the coagulation profile of these patients should be verified for signs of coagulopathy.

Seltene Ursache chronisch rezidivierender Lungenembolien und pulmonal-arterieller Hypertonie

HISTORY AND CLINICAL FINDINGS

A 41-year-old man with known Klippel-Trenaunay syndrome was admitted to hospital because of progressive dyspnea on exertion. Examination on admission revealed the typical signs of Klippel-Trenaunay syndrome, predominantly of the left leg.

INVESTIGATIONS

D-dimers were significantly increased. Contrast-enhanced computed tomography of the chest revealed multiple small pulmonary arterial emboli in subsegmental arteries on both lungs. Pulmonary arterial digital subtraction angiography revealed extensive peripherally localized perfusion defects. Pulmonary artery pressure measurement demonstrated bilateral pulmonary artery hypertension. Phlebography of the left lower leg showed marked varices in the calf. There was also a persisting sciatic vein.

DIAGNOSIS, TREATMENT AND COURSE

The recurrent peripheral pulmonary emboli with pulmonary arterial hypertension was a complication of a Klippel-Trenaunay syndrome. Another rare entity of this syndrome was a persisting sciatic vein. Heparinization was initiated, followed by oral anticoagulation. As the patient had not been anticoagulated before, implantation of an inferior vena cava filter was not deemed appropriate.

CONCLUSIONS

Recurrent peripheral pulmonary emboli leading to chronic pulmonary artery hypertension is a rare but typical complication of Klippel-Trenaunay syndrome. Early recognition of this syndrome and any complications as a separate entity, as well as initiation of therapeutic measures, like anticoagulation or early pulmonary thrombendarterectomy for chronic pulmonary artery emboli, are of prognostic importance.

[Klippel-Trenaunay syndrome and bone scintigraphy. A case report]

A 34-year-old man with Klippel-Trenaunay syndrome (KTS) was performed three bone scintigraphies. The first one to evaluate the possibility of avascular necrosis of the femoral head. Secondly, to dismiss a reflex sympathetic dystrophy in the affected lower limb and finally, due to knee pain. Magnetic resonance of pelvis and knee and biopsy of iliac spine were performed too.

Klippel-Trenaunay-Type Syndrome in Pregnancy

INTRODUCTION

Klippel-Trenaunay-Type Syndrome (KTTS) is a rare congenital anomaly with variable expression and an unknown etiology characterized by capillary and venous malformations and hypertrophy of bone and soft tissue. Pregnancy has been rarely reported in patients with KTTS and since 1989 there have been only 13 case reports of pregnancy in women with KTTS reported in the literature. Concurrent pregnancy is associated with adverse perinatal outcomes. To the best of our knowledge this is the second reported, and largest, series of cases.

STUDY DESIGN

After a thorough review of the literature, the medical records of four obstetrical patients with KTTS were reviewed.

RESULTS

The obstetrical course of women with KTTS varies. Complications include bleeding, DIC, thromboembolic events, and pain.

CONCLUSIONS

The maternal and fetal risks associated with pregnancy in women with KTTS are proportional to the severity of disease, which can be exacerbated by pregnancy. Thoughtful preconceptional counseling, along with methodical and systematic intrapartum and postpartum care are keys to reducing mortality and morbidity.

Cardiovascular collapse during ethanol sclerotherapy in a pediatric patient

Ethanol sclerotherapy is a first line management therapy for low flow vascular malformations. It is usually performed under general anesthesia because of the pain associated with ethanol injection. Ethanol sclerotherapy frequently produces minor local complications but may rarely produce catastrophic cardiopulmonary complications. This report describes the cardiovascular collapse associated with an ethanol sclerotherapy procedure in an 11-year- old child. The evidence for ethanol-induced cardiovascular derangements is discussed.

Venogenic erectile dysfunction in Klippel-Trenaunay syndrome

OBJECTIVE

To report the management of erectile dysfunction (ED) secondary to Klippel-Trenaunay syndrome (KTS), a rare congenital vascular disease.

PATIENTS AND METHODS

Three men (mean age 33 years) with vasogenic ED secondary to KTS underwent venous ligation surgery of the affected veins. These men had tried various treatments for their ED, including phosphodiesterase type 5 inhibitors and intracavernosal injection therapy, with little success.

RESULTS

There was abnormal penile venous drainage in all three men, probably associated with congenital vascular malformation from KTS. After venous ligation the men were followed for 5 years and all reported good quality erections satisfactory for sexual intercourse.

CONCLUSION

ED in men with KTS may be due to venous drainage anomalies and if confirmed, venous ligation surgery should be performed as this gives the best chance of a complete resolution.

Klippel-Trenaunay-Weber syndrome involving fetal thigh: prenatal presentations and outcomes

OBJECTIVES

We analyzed the prenatal presentations and perinatal outcomes of Klippel-Trenaunay-Weber syndrome involving fetal thigh in order to provide relevant information for prenatal counseling.

METHODS

We reviewed our own cases and searched for cases from Medline that met the criteria of Klippel-Trenaunay-Weber syndrome involving fetal thigh. Those with isolated hemangioma, hemangioendothelioma, and hemangiolymphangioma were excluded.

RESULTS

The cases of Klippel-Trenaunay-Weber syndrome involving fetal thigh, totaling 21, were collected for analysis. These included 19 cases from Medline search and two cases from our institution. The cases with lesions involving right thigh, left thigh, and both thighs were 12:8:1. The gender of affected fetuses was 9 male, 9 female, and 3 unknown. Among the 21 cases, 6 fetuses (28.57%, 6/21) had isolated thigh lesions, and the other 15 cases (71.43%, 15/21) had extensive lesions involving pelvis, abdomen, retroperitoneum, or thorax. Prenatal presentations varied with hypoechoic cystic mass with limb asymmetry, 95.23% (20/21); polyhydramnios, 38.09% (8/21); cardiomegaly, 19.04% (4/21); thick placenta, 9.52% (2/21); nonimmune hydrops fetalis, 9.52% (2/21); and oligohydramnios, 4.76% (1/21). Ten cases (47.62%, 10/21) underwent termination of pregnancy. For those who continued with pregnancy, the rate of complications with Kasabach-Merritt syndrome was 36.36% (4/11) and the mortality rate in the neonatal period was 45.45% (5/11). The causes of neonatal mortality in these five cases included consumption coagulopathy (Kasabach-Merritt syndrome), cardiac failure, sepsis, and prematurity.

CONCLUSIONS

Klippel-Trenaunay-Weber syndrome involving fetal thigh is rare. Our review showed that the location of involvement on the right thigh is more than on the left. Males and females were equally affected. Nearly three fourths of the cases had extensive involvement over other parts of the body. Prenatal ultrasound finding of a raised thigh mass of significant size and limb asymmetry were the most important features. The mortality rate was as high as 45.45% in the neonatal period.

Extensive cervical-mediastinal cystic lymphatic malformation treated with sclerotherapy in a child with Klippel-Trenaunay syndrome

Klippel-Trenaunay syndrome is a rare congenital disorder characterized by combined vascular malformations, varicosities, and limb enlargement. A child case of Klippel-Trenaunay syndrome with a large cervicomediastinal cystic lymphatic malformation and a vascular mass on the chest wall has been presented to demonstrate combined use of conservative and surgical approaches in this syndrome. Cystic lymphatic malformation was treated by sclerotherapies including ultrasound-guided transthoracic bleomycin injection into mediastinal cyst, which was tried for the first time in the literature, and vascular chest wall tumor necessitated surgical excision.

Pulmonary embolism in a patient with Klippel-Trenaunay-Weber syndrome

Klippel-Trenaunay-Weber syndrome (KTWS) is a congenital disorder characterized by cutaneous capillary malformations, venous-lymphatic anomalies, hypertrophy of soft tissue and bone in the area of increased vascularity and arteriovenous fistulas with shunting. In this article we report the case of a 25 year old man with KTWS who had multiple surgical operations because of arteriovenous malformations. He admitted with pulmonary embolism attack to the hospital although he was taking prophylactic heparin treatment. We evaluate the risk of pulmonary embolism in patients with KTWS, being aware of the risk of deep venous thrombosis in progress of the disease and the importance of early diagnosis in prognosis.

Klippel-Trenaunay syndrome with small vessel pulmonary arterial hypertension

A patient with Klippel-Trenaunay syndrome and pulmonary arterial hypertension not associated with chronic thrombo-embolic pulmonary hypertension is described. It is hypothesised that pulmonary arterial hypertension is another complication associated with the Klippel-Trenaunay syndrome, possibly due to haemodynamic changes of small vessel abnormalities.

An infantile case of Sturge-Weber syndrome in association with Klippel-Trenaunay-Weber syndrome and phakomatosis pigmentovascularis

Sturge-Weber syndrome can be associated with facial port-wine stains and intracranial calcification, and concurrent Klippel-Trenaunay-Weber syndrome has been reported. Klippel-Trenaunay-Weber syndrome is a rare congenital mesodermal phakomatosis characterized by cutaneous hemangiomas, venous varicosities and soft tissue or bone hypertrophy of the affected extremities. This report is presented a rare case of the Sturge-Weber syndrome in combination with the Klippel-Trennaunay syndrome and phakomatosis pigmentovascularis in a 4-month-old infant. He showed nevus flameus on the right leg and both part of the face and back, leptomeningeal angiomatosis on right hemisphere, hypertrophy of the right leg, hemiconvulsion on the left and also evidences of congenital glaucoma and nevus of Ota. Very rare case combined with these three kinds of phakomatosis has been reported.

Neuroradiologic findings in a young patient with characteristics of Sturge-Weber syndrome and Klippel-Trenaunay syndrome

The patient presented here has extensive hemangiomata plana, especially on the right forehead, right upper eyelid, and right leg, as well as right leg hypertrophy and macrocephaly. Cerebral magnetic resonance imaging (MRI) showed abnormalities in only one occipital lobe consisting of focal cortical atrophy, leptomeningeal enhancement, and ipsilateral choroid plexus enlargement. Mental and motor development is normal, and he has no seizures. The parents are consanguineous. Leg hypertrophy associated with ipsilateral cutaneous vascular malformations is suggestive of Klippel-Trenaunay syndrome. The patient's central nervous system abnormalities on MRI and the hemangiomata plana on the ipsilateral upper eyelid and forehead point to Sturge-Weber syndrome. We conclude that the patient has an overlap syndrome between Klippel-Trenaunay syndrome and Sturge-Weber syndrome.

Klippel-Trenaunay syndrome associated with polydactyly

Klippel-Trenaunay syndrome (KTS) manifests cutaneous vascular nevus, superficial venous varicosities, and hypertrophy of the affected limb. KTS may be associated with other developmental anomalies such as polydactyly, syndactyly, and macrocephaly. We present a case with KTS associated with polydactyly.

Pulmonary thromboembolism associated with Klippel-Trenaunay syndrome

Klippel-Trenaunay syndrome (KTS) is a rare congenital anomaly characterized by unilateral limb overgrowth, venous varicosities, and capillary malformations (port wine stains) of the affected limb or limbs. Large venous malformations such as those observed in KTS are rare, and many physicians are unfamiliar with the potential complications, which include hypercoagulability, thrombosis, and pulmonary embolism (PE). As a result, patients may suffer from delayed diagnosis of a potentially life-threatening thromboembolic event. We present 2 cases of children with KTS complicated by PE, and we review the English-language literature regarding pathophysiologic features, interventions, and outcomes of PE in the setting of KTS among both pediatric and adult patients, with emphasis on issues relevant to pediatricians.

Palatal expansion and the Klippel-Trénaunay-Weber syndrome

A girl (aged 8.5 years) with Klippel-Trénaunay-Weber syndrome received orthodontic treatment that included rapid palatal expansion. The patient had early and complete intraoral dental eruption with a posterior crossbite and an expressive transverse atresic maxilla. No carious lesions were found, but hemangioma-like changes of the mucosa were observed. A Haas palatal expander was activated for 15 days and remained in the oral cavity for splinting purposes for 6 months; it was then replaced by a removable acrylic plate with a Hawley arch. Klippel-Trénaunay-Weber syndrome did not impede rapid maxillary expansion, and the treatment was successful.

Klippel-Trenaunay syndrome

Klippel-Trenaunay syndrome (KTS) is a congenital disorder characterized by triad of vascular nevi, venous varicosities and hyperplasia of soft and hard tissues in the affected area. This syndrome usually affects the extremities but occasionally can manifest in the craniofacial region, including the oral cavity. We report a case of KTS and discuss the oro-surgical and dental considerations regarding hemorrhagic tendencies caused by the known local anomalies such as vascular malformations associated with this syndrome as well as systemic abnormalities.
